l'lall'wlt'omfimayfcom/carni.' I 1 B'e itf'known` that- I, ARTHUR HEDLY, a citizen Vof the, UnitedStates;V and aresildent ofChicago, county of @ook andt State of'lllinois, have invented anew and useful linprovement in Punches forI Making Typograph-Matrices and the like, off which the following is a specification, the principle of the invention being herein 'explained' and the-best modeV in which- I have contemplated applying that principle, sov as to distinguish it; fromY other inventions; y'

The present'v improvements relate, as indicated, Vto the manufacture of matricesl for typographs'and. comprise more especially in'm'y application iled August 2'1, 19114, Serial No; 857,868, (sin-ce issued into Patent No. 1,237,643, dated 'August 21, 1917) for` manufacturev of matrices for typogra-phs; which were required to be divided' out of said'v application. p Thesey Vfeatures refe-r primarily to the construction of the punch usedin:Y forming thev intaglio character-ihr pressions in the matrix'bars or blanks, the object being to secure uniform depth of stri-ke throughout the entire extenty of the impression, irrespectiveY ot variations in width ,or confirmation of the character.

To the'accomplishment of the foregoing and related ends, said' invention, then, consisting 'oi the mechanism hereinafter fully Vvdescribed and particularly pointed'v out in `the claims, the annexed"v drawing and the followingV description setting forth in detail certain means for carryingk out'the invention, such disclosed means illustrating, however, but one of various ways in' which theprinciple'of the' invention may be used.

Figs". 8, 9 and l04 are transverse sections of suchfraised1 characterv takeni on thefplfane-indicated1 hy the lines 8--83VA 9 9 and 10-10, respectively, on Fig; 6.- v `Y The onlyI portion-s of the general'5 mechanfi'sm that require tobe described, or-v even referred to, in the present connection-'arethc bed I and the 'punch head 7', these parts beingy -rel'ativelyf'reciprocable so as tof alter# natively advance and-'retract the punch B with `respect to the matrix bar or plate A, shown as held' in operati-ve'positionL on the bed Il. The details of the* mechanism whereby successive bars A may be brought in position for punching, andthere'held in the mannerillustrat'edi'in the l-figure 1 in question, form no part of the presentinvention. The same is; true of the details of' constructio-nof the head 'vwhereby the pufnch Bis adjustably supported tol-vary the depth of the'strike aswell as to proper-ly locate it with respect to the matrix 'bar or plate 135i.v l The Vgeneral"form'of the punch B employed'i-n driving cliaractereimpressions into the blank matrix bars vis indicated in Fig. 1, butv shownf ini moredetail in lFig. t. From these -figures'itwill be noted that the lower end I) ofthe'punch is formed'to enter the ree cess a in the opposed edgeof-the matrixl bar l(see Figi-2), such recess being a Icharacteristicl feature of the' particular barsin hand, Vand it being understood that thef'aee v1oi the VVpunch may kbe changed in form to 4suitthe kind of matrix bar;

instead of'by'b'eing' engraved, that'eonsiderable difficulty' is encountered in forming an intaglio impression 1n themetal "of the matrix bar,whili *will be of uniform :depth throughout, is `fnecessaryif the raised :typ'echaracter 'subsequently 'cast' vfrom such 'Y impression isf to have aperfeet'lyfvplaile printing face. It does not suiice to have the punch face perfectly plane, for I have found.

what exaggerated fashion in the figure in questionA and in VFigs. 17 to 10 inclusive.

. Whensuch a die is impressed into lthemaf terial of the blank, while the vl: 1,ppr=: d -0Ey portions do not penetrate as deeply as the broader portion, the result .will be an` intaglio impression having its bottom insubstantially the same plane. y I, There will, ofcourse, be a ,different punch foreach character, andthe body,l of such punch will correspond in its vrcross-sectional dimensions with those of the matrix, being just a trifle less, so that the punch may move freely in the well or recess in the bottom of which the matrix blank is held gripped betweenthe chuck jaws. As a matter of fact, as explained before, it is the bed kI of the machine,y with such chuck jaws' and matrix blank, thatfare moved relatively to the punch, rather than vice versa, vthe range of .movement being slightsince. it is only necessary to lowerthe blank sufficiently Vto allow the punch toclear the recess a in such blank, and thus permit of the insertion of a second blankafter the characterfimpression has been struck in thefirst.

' Theu-pwardmovement of thebed of the machine carrying the"blank, Yis limitedv by the engagement of the 'flat upper faces 'of thechuck jawsj witha plate secured to the under side of the head 7, and ,forming part Vof the means whereby the punchissecured Vto such head.

In order to adj ust `the depth of the strike, since the bed and the head thus occupy a fixed relation at the endv ofthe punching stroke of vthe press, 1it is lnecessary tov pro vide for the vertical adjustment of the punch. The plate 60, just referred to',is accordingly' slidablyrheld in ways S61 ina second plate 62. ,directly `attached to the under sideof the head, saidwaysinclining slightly to thehorizontal, as indicated in Fig. 1. The first-named plate 6 0fis provided with an under-cut slot 63`adapted toreceive and slidab-ly. hold `blockv64f to `T`shape,f to vwhich in turn is attached the punch' B by means of a screw 65,passing through the upper end of the same, Vand;l the depending portion of such block 64;,` Obviously if the ,slida'ble plate 60,be movedralong Vsupportiruggways- 61- in Vthe other: plate, the punch and its supportingblock being held Yagainst Y :such movement by reason of the engagement I.therefore parti i1 of the former in the well 17 between the chuck jaws, such punch will be slightly raised, or lowered, depending upon the direction of movement of saidjplate 6 0.

Such movement is eected by means of aA threaded spindle 66 rotatably .butulongif tudinally immovably heldfi'n'a bracket? attached to. thefront face 'of' the head 7. lThe outer end of such spindle is provided with a hand-wheel 68 tol facilitatel its rotation, while the threaded portion thereof en# gages* with an upwardly projecting arm-69 oath@ platel Bymeans QfSuCh-,Srwsnd the slightangle ofthe ways, it will obviously be possible to secure a very fine adjustment of the punchyvertieally inlthewelh and thus. obtain a Vstrike of exactly 4Vthe depth desired in the production of any given character impression. Byprovidinga micrometer s cale',(not shown) in connectionwith the wheel 6 8, or other` movable part associated with; Ythe* adjustment of the punch, thecorrect position ofparts for any particu; lar punch, onceascertained', can be readily returned towhen the punch is used again,

such .correct position jbeing empirically de -I termined in the first g instance. other words, the character impression is struckin the blank matrix, and the depth ofsuch im-v pression is then carefully gaged by means A ibo other words, I have found that it isgmuch Y Y more advantageous to measure the ,drive from the back ofthe 'bar instead of from its face. This distance a (Fig. 5) being preserved accurately, ythe distance a2 between the front and back faces of thematrix bars ,i

may in turn bemeasured with reference to the same backs, Vand* thusrthe depth ofthe impressions below the plane of such4 faces 'be likewise: accurately "sdetermined,v This method of gagingthe location Yorfdepth of the vcharacter impressions in matrices ofthe. kind in hand, has, so faras I fam aware, never beenattempted before.
